Does​

Answer 1

Answer:

Explanation:

Ecological pyramids are of three general types namely:

(i) Pyramid of numbers, showing the number of individual organisms at each level.

(ii) Pyramid of biomass, showing the total dry weight and another suitable measure of the total amount of living matter, and

(iii) Pyramid of energy, showing the rate of energy flow and/or productivity at successive trophic levels. Pyramids of numbers show the number of organisms at successive trophic levels. In grassland, the producers, which are mainly grasses are always at the base of the pyramid. The producers, which are mainly large-sized trees, are lesser in number and form the base of the pyramid. The herbivores, which are the fruit-eating birds, insects are more in number than the producers. Then there is a gradual decrease number of successive carnivores, thus making the pyramid again upright. Thus, the correct answer is option D.
